Embodiment 1
[0023] Example 1, as Figure 1-2 As shown, a stainless steel blackening treatment heating box includes a box body 1 with an open upper end, a groove 11 is provided on the side wall of the open end of the box body 1, and a cover plate 2 is arranged in the groove 11, and the cover plate 2 A liquid inlet pipe 3 is arranged on the top, and a spiral heating pipe 4 is arranged at the bottom of the box body 1; a tray 5 for holding the stainless steel pipe is arranged on the upper side of the heating pipe 4. It is fixedly connected with the inner wall of the box body 1, and the other two sides are suspended. The suspended position can become the circulation channel of the blackening treatment liquid in the box 1 . The heating tube 4 includes an inlet tube 41, a spiral tube 44 and an outlet tube 42, the outlet tube 41 is located at the lower side of the center of the spiral tube 44, and the outlet tube 42 is connected to the spiral tube 44 through a downward bend 43. Connected. A li...

The invention relates to a heating box for stainless steel blackening, which comprises a box body with an opening at the upper end, and a cover plate for sealing the opening of the box body, wherein the cover plate is provided with a liquid inlet pipe, and the bottom in the box body is provided with a spiral heating tube; and the upper side of the heating tube is provided with a tray for supporting a stainless steel tube, two lateral sides of the tray are fixedly connected with the inner wall of the box body, and the other two lateral sides are suspended. By designing the new position of the heating tube, the heating box liberates the heating space, avoids the contact between the stainless steel tube and heating tube, and is convenient for the operating personnel to put in and take out the stainless steel tube.
Description
technical field [0001] The present invention relates to a process device, especially a heating device, used in a stainless steel surface treatment process. Background technique [0002] Blackening is a common method of chemical surface treatment. The principle is to produce an oxide film on the metal surface to isolate the air and achieve the purpose of rust prevention. The control of heat in the blackening process is also an important indicator to improve the blackening process. [0003] For example, a blackening device for round steel product quenching and tempering treatment production line according to Authorized Announcement No. CN201933156U, although the structure is simple, the blackening treatment process is simple, and the production efficiency is high, but the blackening treatment process lacks heating and heat preservation links, resulting in energy The consumption is large, and the cost will increase accordingly. SUMMARY OF THE INVENTION [0004] The purpose ...
